Abstract (en)
A blade outer air seal (BOAS) assembly (207) includes a rotor blade (200) configured to rotate about an axis (A-A'). The BOAS assembly (207) also includes a BOAS (208) positioned radially outward from the rotor blade (200) and having a forward-facing BOAS face (332). The BOAS assembly (207) also includes a shroud block (210) positioned radially outward from the BOAS (208), having an aft-facing shroud face (328), and being configured to support the BOAS (208). The BOAS assembly (207) also includes a first bellows seal (324) extending from the forward-facing BOAS face (332) to the aft-facing shroud face (328) and configured to reduce fluid leakage radially between the BOAS (208) and the shroud block (210). A corresponding gas turbine engine is also provided.
